What do you hope to get: a bull, heifer, or a steer prospect? Sorry -didn't read the post close enough to notice what you wanted.
Want a heifer: Yellowjacket all the way.
Want a bull: I'd lean more towards George or Troubador. Troubador if you want to swing for the fence for a steer producer, George if you want more all-around. Troubadors can get real straight, but you should be ok on her. YJ bulls probably aren't as marketable, and you'd only have 1/4 blood Charolais. Most of the crossbred Char bulls that really work are halfbloods.
Want a steer prospect: You need something from the Heatseekr-Heatwave line, hence WJ's recommendation for Lovin the Business (who is a Solid Gold son). I'd probably consider Solid Gold himself also. George is a no for steers, Troubador works best on TH carrier cows. Yellowjacket steers are too big and too hard to finish.
